The 2020- and 2021-series devices are fixed, single-input, single-output, passive delay lines. The signal input (IN) is reproduced at the output (OUT), shifted by a time (TD) given by the device dash number. The characteristic impedance of the lines is nominally 50 ohms. The rise time (TR) of the lines is no more than 1ns, resulting a 3dB bandwidth of at least 350MHz.

Network analyzer is used in phase measurement mode, normalized with a wire jumper between input and output of DUT test socket. Delay is related to phase lag with proportionality constant of 100ps/deg. NOTE: The above conditions are for test only and do not in any way restrict the operation of the device.
